SLIDE 12

~ 13 700 known NEOs …of which… ~ 510 (4 %) have impact solutions (VIs) in the next century (according to NEODyS and Sentry) However… of those VIs:

  • Only ~2 % have more than one apparition
  • ~90 % are lost!

We need to find a way to improve these numbers by:

  • Prevent the new ones from being lost
  • “Recover” some of the lost ones

NEO Statistics

slide-13
SLIDE 13

There are basically three ways to deal with this problem:

  • Extend the observed arc at the discovery apparition
  • Attempt wide-field recoveries at the next apparition
  • Try to locate precovery observations in existing archives

These goals can be achieved using:

  • Large aperture telescopes
  • Wide-field imagers
  • Large repositories of astronomical images

How to do it

slide-14
SLIDE 14

ESA Optical Ground Station (OGS)

  • Survey (with Matthias Busch)

Discovered 11 NEOs in 2014-2015 1 current VI discovery: 2014 QN266 2 comets, C/2014 C1 (TOTAS) and C/2015 C1 (TOTAS-Gibbs)

A 1.0 meter ESA telescope in Tenerife, Canary Islands We have 4 to 8 nights per month, around new Moon

  • Follow-up

~20 NEOs observed per run We can reach V~22 NEO or comet recoveries every month

slide-15
SLIDE 15

ESO Very Large Telescope (VLT)

  • The faintest NEO ever seen

Observed in September 2015 at V~27.1!

Four large 8.2 meter telescopes at Cerro Paranal, Chile ~11 hours per semester in cooperation with ESO

  • Follow-up and recovery of VIs

FORS2 camera, 7’ FoV More than 30 VIs observed in 2014-2015 We can reach V>26

slide-16
SLIDE 16

Large Binocular Telescope (LBT)

  • The first NEO with LBT

2014 KC46 recovery in October 2014 V=26, uncertainty spanning the whole field

Two twin co-mounted 8.4 meter telescopes Cooperation with the Italian partnership (INAF, Observatory of Rome) for DDT time

  • Simultaneous imaging

Two wide field cameras, ideal for recoveries Capable of reaching V~26 on a 27’ field

Collaborations

ESA Service Level Agreements:

  • Calar Alto Observatory, Spain
  • Kleť Observatory, Czech Republic

Collaborations with existing networks:

  • GAIA FUN-SSO
  • EURONEAR
  • Las Cumbres (LCOGT) Network

Other observatories:

  • Campo Imperatore, Asiago and Loiano, Italy
  • Mauna Kea Observatories, Hawaii, USA

  • …and many others
slide-18
SLIDE 18

Outside sources:

  • Large telescopes (e.g. CFHT, DECam, VST)
  • Asteroid surveys (e.g. Pan-STARRS)

Developing our own archive (integrated with CADC)

  • Images from our observational activities (e.g. OGS)
  • Images from collaborating partners

Precoveries

  • The faintest NEO precovery

2008 CK70, top-10 in the list of VIs 5-day arc, effectively lost Found in CFHT at V=24.5!

slide-19
SLIDE 19

A peculiar artificial object as a test for an NEO impact We alerted our collaborators to obtain:

  • Astrometric observations (Mauna Kea, Asiago, Loiano, OASI, DeSS, Lumezzane, Schiaparelli)
  • Precoveries (Pan-STARRS archive)
  • Colors (Loiano, Asiago)
  • Spectroscopy (Successful DDT at VLT)
  • Lightcurve observations (Asiago, Loiano, Schiaparelli, Lumezzane)
  • Airborne observation campaign (University of Stuttgart)

From… … to

Observation campaigns: WT1190F

SLIDE 28

Core Services: Orbit Visualizer The Orbit Visualization Tool provides a 3D animated display of the asteroid motion by drawing its orbital path and the position of the

  • bject along the orbit.

For NEAs a refined model of the trajectory that includes planetary perturbations is adopted. This enhanced functionality makes use

  • f high-accuracy ephemerides generated by NEODyS to properly

display the orbital changes due to close encounters.

When an object approaches the Earth within 0.02 au it is possible to switch to an inertial geocentric reference frame to visualise the geometry of the encounter and the underlying dynamics. Core Services: Orbit Visualizer

The Priority List supports the task of efficiently planning and executing NEO follow-up observations. It classifies newly discovered objects into four priority categories, which can guide the observer in selecting the most useful follow-up targets. Core Services: Priority List
